Bought a DSI Tempest from neuromodulator.
Over all a good experience for me. Market value for a "like new" Tempest, so no haggling. Delivered promptly as described.
Besides covering all the bases like packaging and communication, he went above and beyond helping me through the buying process. This was my first P2P purchase. He was patient with my questions, did the research on customs (Candada to US) and shared his experience on working with the Tempest. Also found a shipper that would accept the package on Sunday.
Hopefully you get the point ... positive feedback to the max.
